This might not be the most attractive dress in the world, but it has two things going for it – it’s really short and it can change colors. There are more than 400 circuit boards here, each of which is connected to a control unit on the back. Moreover, each board has a solar cell, an RGB LED or a photocell, and a jumper connector. The dress charges during the day, and changes colors when night falls or the light gets dim. You ladies out there can combine geek and chic in one outfit. Believe me, you’ll be a hit at the Star Trek convention.
